Installed my Aliexpress cheap wire feeder board today.
Quite straight forward.
Blue 10 turn pot adjusts minimum speed.
Has a quirk of feeding wire before power contactor closes.
This tends to push touch away from work if you not expecting.
A firm grasp overcomes this.
Burn back at highest current setting is back all but at tip.
Not perfect but over came problems I had using variable voltage controller.
Too much stick out!
On the whole, adequate for the price.
Found a circuit that can do 2t/4t.
Down side is it uses 3 relays.
One would have to have 3 poles of contacts.
At face value, a solution but time and components add up.
Picking 24v AC relays as DC relays have lag on opening.
Yorweld supplies have an excellent universal board that does 2t/4t but price is killer.
Anyone know of another product that does 2t/4t?
